Click event inside sub-viewport

Question

I have a structure with Viewport:

I want to have object (like button) in viewport which allows me to click on it. How I can achieve this?
The events to not work for the Button here

Answer 1

You can forward the input events from one of the Viewport's parent nodes with the Viewport.input(InputEvent local_event) function. In the parent node:

onready var viewport = get_node("Viewport")

func _ready():
    set_process_input(true)

func _input(event):
    viewport.input(event)

You might also have to offset the position of mouse events if your ViewportSprite isn't in the top left corner.

I got it to work with a ViewportContainer:
set the ViewportContainer mouse settings to ignore
then forward the UNHANDLED input to the viewport

onready var viewport = get_node("Viewport")

func _ready():
    set_process_input(true)

func _unhandled_input(event):
    viewport.input(event)

I hope i prevent someone the 4 hours of desperately looking everywhere for a fix i spent :D
